Reflection of 3x+4y+5=0 w.r.to the line 2x+y+1=0 is. ... Reflection of 3x+4y+5=0 w.r.to the line 2x+y+1=0 is. Question from...

General equation of line is ax+by+c=0

Given, line parallel to y-axis means x=0

Put x=0

by+c=0

Distance from origin is +5 units

So equation is y=5

thanks bro

a. Long-sightedness caused by loss of elasticity of the lens of the eye, occurring typically in middle and old age.

Most experts believepresbyopiaiscausedby changestothe lens inside the eye. As people age, the lens becomes harderandless elastic, making it more difficult for the eyetofocus on close objects. For centuriespresbyopiawascorrectedwith the use of bifocal eyeglasses.

b. Light from theSunnear the horizon passes through a thicker layer of air and a larger distance in the Earth's atmosphere before reaching our eyes.

However, near the horizon, most of the blue light and shorter wavelengths are scattered.

The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.

Therefore,For equation 4x + 3y + 12 = 0Convert this equation to standard formy = - 4x/3 - 4

Hence, Intercept for given equation is - 4

Equation of the line segment is 4 * x + 3 * y + 12 = 0,so,x - intercept,put, y = 0,x = - 3,y - intercept,put x = 0,y = -4,hence,intercept of the given line segment 4 * x + 3 * y + 12 = 0 is ( -3, -4 ).

the answer x/2 +y/-3 = 1

the answer x/2 +y/-3 = 1

x/2+y/-3=1 is the right answer

thanks

thank you

The smallest 4-digit whole number is 1000, and its prime factors are2 and 5.

Actually, 2 ^ 3 * 5 ^ 3

For any integer greater than 5, where the units digit is 5 then that number can be expressed as the product of n and 5. As such, the number is composite.

Therefore all numbers in the range 150 to 200 that have a units digit of 5 are composite,.

neet balls = 7+3=10let, 2 black balls =1 black balls now, 9 balls er placed in them is : 9! then the probability that two black balls are adjacent is (9!/10!)= (1/10)now, the probability that no two black balls are adjacent is {1-(1/10)}=(9/10)

Placing 7 white balls in a row leaves 8 gaps.

The 3 black balls can be placed in 8 gaps in 8C3 = 8×7×6/3×2×1= 56 ways.

So, the total number of ways of arranging white and black balls such that no two black balls are adjacent = 56*3!*7!

Actual number of arrangements possible with 7 white and 3 black balls = (7+3)! = 10!

Therefore probability that no two black balls are adjacent = 56∗3!∗7!/10!=7/5∗3=7/15
